Parameter Comparison

Engineering Selection Recommendations

The CAY10A-472J4AS is the qualified substitute for the obsolete CAY10-472J4AS. Both components are manufactured by Bourns Inc. and maintain identical electrical specifications and mechanical compatibility.

The CAY10A-472J4AS offers the advantage of active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting regulatory and environmental requirements.

The maximum seated height difference of 0.002" (0.05mm) between the two parts is within typical PCB assembly tolerances and does not impact functional performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the CAY10A-472J4AS be used as a direct replacement for the CAY10-472J4AS?

A: Yes. The CAY10A-472J4AS is electrically and mechanically equivalent to the CAY10-472J4AS. All critical parameters including resistance value, tolerance, power rating, temperature coefficient, and package format are identical. The substitute part is compatible with existing PCB designs without modification.

Q: What is the significance of the product status difference between these parts?

A: The CAY10-472J4AS is classified as obsolete, while the CAY10A-472J4AS is active. This means the substitute part has ongoing manufacturing support and guaranteed supply availability, making it the preferred choice for new designs and ongoing production.

Q: Are there any height or dimensional considerations when substituting these parts?

A: The seated height differs by 0.002" (0.05mm), with the CAY10A-472J4AS measuring 0.020" maximum versus 0.018" for the original part. This minimal difference is within standard PCB assembly tolerances and does not affect electrical performance or mechanical fit.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both the CAY10-472J4AS and CAY10A-472J4AS are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. They meet identical regulatory and environmental requirements.

Q: What packaging options are available for the substitute part?

A: The CAY10A-472J4AS is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly operations.
